OIL BURNER.

Application filed December 6, 1923.

To all whom it may concern Be it known that I, CHARLES A. JArHE'r, a citizen of the United States, residing at Seneca, in the county of Nemaha and State of Kansas, have invented a new and useful Oil Burner, of which the following is a specification.

This invention relates to an improvement in oil burners adapted to burn any kind of liquid hydrocarbon fuel, provision being made for the introduction of water into the fire chamber and its conversion into steam to mix with the vaporized fuel and increase the efficiency thereof when the heavier liquids are used.

The general objects of the invention are to provide a simple and inexpensive burner structure composed of a minimum number of parts and to provide improved means for introducing and distributing the fuel and water and for controlling the mixing thereof after the same has become vaporized, whereby complete combustion is effected without formation of soot and a hot white flame is emitted.

The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanying drawing which illustrates the preferred form of the invention.

In the drawing:

Fig. 1 is a vertical section through the burner and the associated parts taken substantially on the line 1-1 of Fig. 2.

Figure 2 is a horizontal sectional view on the line 22 of Fig. 1.

Figure 3 is a horizontal sectional view on the line 33 of Fig. 1.

Fig. 4 is a vertical sectional view taken at right angles to the plane of Fig. 1.

The burner structure consists essentially of a base, on which is supported the burner element, and a cap which rests on the burner element and forms in connection therewith a mixing chamber for the vaporized fuel and steam. The base, which is designated 5 in the drawing, is of hollow cylindrical shape adapted to rest upon the grate of a furnace, stove or the like, and is provided on its upper face with a circular flange 6 within which is supported the cylindrical burner element 7.

The base 5 is provided at one side with an opening 8 suificiently large to admit an ample supply of air, and a circular opening 9 in the upper face of the base is coextensive within the pipes.

Serial No. 678,923.

with the inside wall 10 of the cylindrical member 7 The element 7 is provided with an integral flange extending outwardly and upwardly to form an oil channel 12 and having a further extension which forms a water channel 13 concentric to the channel 12 but shallower, the rims 14; and 15 forming the sides of the channels.

The oil is supplied through a pipe 16 which extends through the base and upwardly through the burner element'7 above which it is provided with branches 17 terminating in downwardly-turned nipples 18 and 19 through which the oil may be discharged into the channel 12. Water is supplied through a pipe 20 which may be introduced through the base 5 and provided with upwardly-extending branches 21 and 22 that open into the bottom of the channel 13. A cap 23 is adapted to rest upon the flange 11 inside of the rim 15 so as to enclose the oil and water channels 12 and 13, respectively, and to form a chamber within which the oil and water may be thoroughly mixed after they have become vaporized. A series of openings 24: are formed in the base portion of the cap 23 for the emission of the flames and the products of combustion. A ring or handle 25 may be connected with the cap 23 for removing the same to light the burner.

The base 5 not only supports the burner element at the proper height in the stove or furnace, but is designed for permitting the passage of the oil and water pipes and to protect the same from the direct heat of the fire so that it is impossible for the oil to become converted into gas or the water into steam until they strike the generator plate or flange 11. This eliminates clogging and burning out of the pipes such as results when the vaporization takes place The vaporized oil and the steam, which are formed by the heat of the plate or flange 11, rise within the cap 23, where they become thoroughly commingled and the superheated steam combines with the excess of carbon to form carbon monoxe ide and hydrogen, which, in the presence of an ample supply of air admitted through the opening 8 and passageway 10, are completely consumed and the resulting flames and products of combustion, are. emitted through the openings 24. The burner is constructed of heavy cast iron and has only three parts, the base 5, the burner element 7 and the cap 23; thus it may be produced at a moderate price Within the reach of persons 01 most limited means. The concave cover in connection with the flange 11 forms a chamber Within which the vaporized fuel and superheated steam are thoroughly mixed, thus resulting in a complete combustion and a hot White flame.

While I have shown and described the specific structure of one form-in which the invention may be embodied, it will be understood that various changes may be made in the adaptations thereof Within the scope of What is claimed without departing from the spirit of the invention.

lVhat is claimed is: l

1. In an oil burning device, the combination with a hollow base having a central air opening through its upper Wall, of a burner member formed of a single casting having a central flue and adapted to rest upon the base surrounding said opening With an annular extension having concentric channels in its upper surface for receiving oil and Water res 'iectively, and-a cap adapted to rest on said extension and enclose said channels, said cap being provided near its base with a series of openings for the emission of the flames and products of combustion.

2. In an oil burning device, the combination of a hollow substantially cylindrical burner member having an integral outwardly and upwardly extending flange forming a pair of concentric circular channels, the inner channel being deeper than the outer channel, a base for supporting said burner.

member and providing means for admitting air to the base of the burner, an oil supply pipe extending through the base upwardly through the burner member and having outlets overhanging the inner channel, a Water supply pipe having outlets extending up- \vardly through the bottom of the outer channel, and a cap adapted to rest on said flange and enclose the oil and Water channels and having a series of openings in its base for the emission of the flames and products of combustion' In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.
